Modification of Linear Regression & Correlation Worksheet

Explore linear modeling of bivariate data by moving the data points up and down. You'll see how the correlation coefficient r describes the linearity of the data, and how the least-squares regression line fits the data. The point indicating the mean of the x-coordinates ("x-bar") and the mean of the y-coordinates ("y-bar") is shown. Added is a projection point to facilitate discussion of the predictive potential of the model.
